Network requirements
As shown in Figure
and Switch 2 is dot1q, workstation A and C belong to VLAN 10, and workstation
B and D belong to VLAN 20. It is required that:
The IP addresses of router subinterfaces Ethernet 3/0.10, Ethernet 3/0.20,
■
Ethernet 4/0.10, and Ethernet 4/0.20 are 1.0.0.1/8, 2.0.0.1/8, 3.0.0.1/8, and
4.0.0.1/8.
Work station A can intercommunicate with work station B, and work station C
■
can intercommunicate with work station D, that is, devices connected to the
same switch but belonging to different VLANs can intercommunicate with each
other.

Description
-
Required
If the specified ATM sub-interface does not
exist, this command first creates the
sub-interface and then enters the
sub-interface view.
By default, point-to-multipoint
sub-interfaces are created.
